VEHICLE-WHEEL RIM.

PatentedJuly 13, 1909. Serial No. 379,029.

To all whom it may concern: I

Be it known that I, EDWIN CoUPLAN SHAW, a citizen of the United States,and a resident of Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful Improvements in Vehicle-Wheel Itims, ofwhich thefoll wing is a specificatron.

This invention relates to that class of vehicle wheel rims adapted forholding pneu- -matic tires, or other tires of resilient material \inwhich one of the-tire retaining flanges is made removable.

It has been customary in rims for holding l pneumatic tires to make bothof the tire retaining flanges fixed, but this arrangement makes theapplication of the tire difficult, and renders it impossible touse tiresof the type provided with inextensible beads. By

'20 making one of the retaining flanges removable, it is obvious that atire can be applied to the rim without stretching so that aninextensible tire can be used just as well as one of any other type. Inthis case specific '25 means are provided for holding the removableflange in place, these means comprising a locking ring adapted to liewithin a groove formed at the edge of the tire seating memher andprovided with expanding means whereby it will be caused to enter agroove formed in the inner face ofthe removable tire flange and preventthe flange from slipping off its seat.

Referring to the drawings which form a part of this specification,Figure 1 is a sectional perspective view of a rim and tire illustratingone-form of my invention. Fig.

2 is a seetion of the rim and tire shown in Fig. 1 taken on line II-IIof Fig. 3.

Fig. 3 is a side elevation of the rim and tire shown in Figs. 1 and 2.Fig. 4 is a plan view of the tire seating member showing the cutoutportion to receive the ring expanding means. g

Referring to the drawings by reference nu- *merals, 1 is the folly uponwhich isfixed in i any suitable manner a tire seating member or fixedrim 2. This rim is, shown'as provided at one edge with a fixed tireretaining flangev 3, though this flange may be detachable if desired.The other edge of this rim 2 is provided with a seat 5 upon which fitsan endless detachable flange 6. In .thisexample/of m invention the seat'5 is shown as incline downwardly and outring 8.

l flange 6 is provided with a groove 9 to receive I k v E I I n r theouter portion ol the lockmg ring. 'llns 0 made.

lwardly to facilitate the positioning of the flange 6, and to make asnug tapc r flt with the flange but the incline is not necessary and theseat may be given any form so long as it does not project above thelevelof the (in tire seating portion. An annular groove 7 is formed inthe seat in which lies a locking The inner face of the tire retaininggroove and the said outer portion of the locking ring are in the examplechosen for purposes of illustration shown as correspond ingly V-shaped,but it is obvious that any other configuration may be used.

Means are provided for contracting andexpanding the locking ring. Thesemeans are herein shown as conmrising a turnbuckle 10 into which the endsof the locking ring screw. The turnbuckle is provided with 7d sockets 11or other suitable means for cngagement of a tool for rotating it. Thegroove 7 must be of such depth that when the ends of the locking ringare drawn together, the ring will lie wholly within the groove, thuspermitting the flange (i to slide freely oil its seat. A slot 12 ofsuitable form and dimensions is cut in the rim to roceive the turnbuckle10 and permit it to be manipulated. r

The operation of the device is as follows: To remove the flange theturnbuckle is operated to bringthe ends of the locking ring togetherwhen the flange and tire can be freely removed. To apply a tire it isslipped into place and fitted to the flange 3 and the removable flange 6slipped on its seat andengaged with thefoot of the tire. The ends of thelocking ring are then spread apart by means of the turnbuckle, thusincreasing the diameter of the ring and causing it to engage the groove9 in the inner surface of the retaining flange 6, locking the retainingflange and tire firmly in position. have shown the flanges formed toengage a clencher tire, but it is obvious that they may be given asuitable configuration to retain any other type of tir...

Ido not desire to limit myself to the exact construction shown, whichhas been chosen merely as an illustration of one form in which myinvention may be embodied since modifications may be freely made which Idesire to cover so long as the operative combination of elements isretained.

Having thus described my invention I claim:

1. In combination in a vehicle wheel, a tire seating member provided atone edge With a downwardly and outwardly inclined seat, an annulargroove in said seat, an endless tire retaining flange adapted to engagesaid seat, a groove in the inner surface of said flange, a locking ringprovided with av V-shaped outer face in the groove of said tire seatingmember, and means for expanding and contracting said locking ring.

2. In combination in a vehicle wheel, a

tire seating member provided With an annu- I lar groove, an endless tireretaining flange adapted to seat upon said member over said groove, alocking ring in said groove, a V shaped groove in the inner surface ofsaid endless flange, said locking ring being provided with a V-shapedouter face adapted to enter said V-shaped groove, and means forexpandingand contracting said locking ring.
